Potomac River Running welcomes MMM supporters all year long, but especially during the month of March, in support of Children’s National Medical Center, the region’s leading pediatric hospital. Children’s National is one of the nation’s top 10 children’s hospitals, and each year, Children’s National serves more than 200,000 children from Washington, Maryland, and Virginia. Your support of the Make March Matter campaign will help ensure that every child, from every background and every walk of life, can receive exceptional and compassionate care!
